Abstract
Background: Volleyball is an intermittent team sport that requires speed, explosive power, jumping ability and rapid changes of direction. Plyometric training uses rapid stretch-shortening cycle movements and is commonly applied to improve explosive athletic performance.
Objective: To evaluate the effectiveness of an 8-week plyometric training programme on speed and explosive power among male volleyball players.
Methods: A pre-experimental single-group study was conducted among 30 male volleyball players aged 18–23 years. Participants were selected using purposive sampling. Plyometric training was provided three days per week for 8 weeks. Each 60-minute session consisted of 10 minutes of warm-up, 40 minutes of plyometric training and 10 minutes of cool-down. Speed was assessed using the 40-m shuttle run test and explosive power using the standing broad jump test. Measurements were obtained at pre-test, post-test I after 4 weeks and post-test II after 8 weeks.
Results: Mean 40-m shuttle run time decreased from 11.42 ± 0.743 s at pre-test to 11.02 ± 0.582 s at post-test I and 10.57 ± 0.558 s at post-test II. Mean standing broad jump distance increased from 174.86 ± 8.15 cm to 180.43 ± 8.32 cm and 186.26 ± 8.44 cm, respectively. Repeated-measures ANOVA reported significant differences across the three assessment points for both outcomes (p = 0.001).
Conclusion: The findings indicate that the 8-week plyometric training programme was associated with improvement in speed and lower-limb explosive power among male volleyball players.
